On Mar. 14, 2025, the Michigan Department of Health and Human Services (MDHHS) and Oakland County Health Division have confirmed an adult case of measles in Oakland County. This was the first confirmed case of measles in Michigan this year and the first case since July 2024.

The infected adult had recent overseas travel and their vaccination status was unknown.

Measles is a highly contagious, vaccine-preventable disease that is spread by direct person-to-person contact and through the air. MDHHS recommends unvaccinated individuals ages 1 year and older receive measles vaccination to protect themselves and those around them.

If you think you were exposed to measles on or after March 10, Immune Globulin (Ig) treatment is effective within six days of exposure for high-risk individuals. High-risk individuals include those who are pregnant and those who have a weakened immune system due to illness and disease including diabetes or HIV, malnutrition and/or medications.

Measles can live for up to two hours in the air where an infected person coughed or sneezed. Symptoms of measles usually begin 7-14 days after exposure, but can appear up to 21 days after exposure.
